Telecom Interface LE88241DLC™ Tracking Battery ABS (Automatic Battery Switching) VoicePort device implements a dual-channel telephone line interface, providing all the necessary voice functions from a high voltage subscriber line interface to a μP/DSP digital interface. Telecom Interface LE88241DLC This ABS device can be powered from an external battery, or run from power generated by an on-chip switching regulator controller. The device reduces system-level cost, space and power consumption by enabling the highest possible level of voice integration. Designers benefit from having a simple, economical, low-power and dense interface design without sacrificing functionality or functionality.

The programmable, telecom interface LE88241DLC feature-rich voice port device provides a powerful line interface for short and medium loop (up to 1500 ohms per person) application requirements. Features include: high voltage switching regulator, self-test, line test capability, telecom interface LE88241DLC integrated ringer (up to 110-Vpk), global software programmability, flexible signal generator with tone cadencing, caller ID generation and all borsson Function. The capabilities of these voice port devices are critical to designing cost-effective, full-featured broadband voice solutions
